Description

Technical Field

[0001] This utility model relates to the field of heater technology, specifically to an air conditioning device and a heater. Background Technology

[0002] Currently, in related technologies, some users typically use fan heaters for warmth, but some existing products use electromagnetic heating. However, the operation of electromagnetic heating involves a large number of electronic components. In order to achieve a better heating effect, the heating element will generate a lot of heat, which will affect the normal use of electronic components. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0004] In view of the above, an embodiment of the first aspect of the present invention provides an air conditioning device.

[0005] A second aspect of this utility model provides a heater.

[0006] To achieve the above objectives, an embodiment of the first aspect of this utility model provides an air conditioning device, comprising: an outer casing; a heating device disposed inside the outer casing; an air guide shroud disposed corresponding to the heating device, the heating device being used to heat the air guide shroud; an airflow regulating component disposed inside the air guide shroud, the airflow regulating component being used to discharge air toward the inner wall surface of the air guide shroud; a heat insulation bracket disposed outside the air guide shroud, the air guide shroud being disposed on the heat insulation bracket; and a heat insulation layer disposed between the air guide shroud and the heating device.

[0007] The air conditioning device according to this utility model mainly includes an outer casing and a heating device, an air guide shroud, and airflow regulating components disposed within the outer casing. Specifically, the outer casing provides a robust protective shell for the air conditioning device, protecting the internal structure from damage and providing heat insulation and electrical insulation to ensure user safety. The heating device is the core of the air conditioning device, responsible for converting electrical energy into heat energy. The heating device is positioned corresponding to the air guide shroud, raising its temperature. Specifically, the heating element can be an electromagnetic coil. The air guide shroud is located near the heating device and is heated by it. The specific shape design of the air guide shroud should facilitate uniform airflow distribution and efficient heat exchange.

[0008] It is important to emphasize that a heat insulation layer is installed between the air guide shroud and the heating device in this solution. This reduces the impact of the high temperature of the air guide shroud on the temperature of the environment where the heating device is located, improves the safety of use, and also helps to protect the heating device and extend its service life. In particular, it reduces the impact of the heating device on the temperature of internal electronic components and related structural parts, and reduces the possibility of damage to structural components or electronic parts due to high temperature.

[0009] The insulation layer can isolate the air guide and the heating device to a certain extent, reduce the conduction of heat to the heating device, thereby reducing the temperature of the heating device and improving the safety of use.

[0010] It is understandable that air conditioning equipment primarily converts electrical energy into heat and mechanical energy to generate hot air. In this solution, by adding airflow regulating components and an air guide shroud, air is blown towards the air guide shroud by the airflow regulating components. The air guide shroud is heated by the heating device, which increases the temperature of the air blowing towards the air guide shroud. At the same time, the structural features of the air guide shroud itself can guide the airflow to the outside of the air conditioning equipment, thereby providing warm air with a higher wind speed.

[0011] In some technical solutions, the airflow regulating component may optionally include: a fan wheel, located inside the air guide shroud, which rotates to discharge air toward the inner wall of the air guide shroud, and the air is discharged outward from the front side of the outer casing; and a motor, the drive shaft of which passes through the fan wheel and is used to drive the fan wheel to rotate.

[0012] By adjusting the relative positions of the motor and impeller, and by adding a structural guide shroud, air is blown towards the shroud by the impeller. The shroud is heated by the heating device, which increases the temperature of the air blowing towards it. At the same time, the structural features of the shroud itself can guide the air to the outside of the air conditioning equipment, thereby providing warm air with a higher wind speed.

[0013] The impeller, located inside the air guide shroud, generates a powerful airflow as it rotates. This airflow is heated as it passes through the heated shroud and ultimately exits from the front of the turbine head. An electric motor provides the power to rotate the impeller. The motor is designed to ensure sufficient torque to drive the impeller while also possessing good heat resistance.

[0014] It should be added that the motor type can be DC or AC, or even a brushless motor to improve efficiency and reduce maintenance; the motor power and speed must be matched with the design of the impeller; and the motor's heat dissipation design must ensure that it does not overheat during long-term operation.

[0015] In some technical solutions, the insulation layer can optionally be an insulation support, which is located on the outside of the air guide shroud; the thermal conductivity of the insulation layer is less than that of the air guide shroud.

[0016] In this technical solution, by placing a material with low thermal conductivity directly outside the air guide shroud, i.e., the insulation layer is in the form of a support, a heat insulation support is formed. The low thermal conductivity of the material itself can prevent heat from being conducted to the other side of the heat insulation support, thereby ensuring the stable operation of the internal structure.

[0017] The air guide cover is fixed to other structures through a heat insulation bracket. It can be directly fixed to the outer shell or fixed to the heating device. The heat insulation bracket can serve as a support structure for the air guide cover to achieve the limiting function.

[0018] It is understandable that in this solution, the air guide shroud is located inside the outer casing, and its relative position to the outer casing can be restricted by the heat insulation layer, that is, the heat insulation layer fixes the position of the air guide shroud inside the outer casing.

[0019] It is understandable that by setting up an insulation layer, the high-temperature resistance requirements of the insulation bracket can be reduced, which helps to reduce costs.

[0020] In some technical solutions, optionally, the insulation layer is located on the inner side of the insulation support, and the insulation layer includes multiple insulation chambers, with any two adjacent insulation chambers separated by ribs.

[0021] In this technical solution, by setting multiple heat insulation chambers on the inner side of the heat insulation bracket, physical heat insulation can be achieved by utilizing the structure of the heat insulation chambers and filling them with gas. That is, by utilizing the heat insulation properties of the heat insulation chambers themselves, the heat transferred from the air guide hood to the heat insulation bracket can be blocked.

[0022] In some technical solutions, optionally, each insulated air chamber is filled with an insulating medium, the thermal conductivity of which is less than that of the air guide hood.

[0023] In this technical solution, by filling the insulation chamber with an insulation medium with low thermal conductivity to form a continuous insulation structure, heat conduction can be effectively reduced, ensuring the normal use of the insulation bracket and its related electronic components or mechanical structures.

[0024] Alternatively, the insulation medium can be air. When heated, air expands in volume and decreases in density, causing hot air to rise and cold air to sink (natural convection). In the case of convection, heat is mainly transferred through convection, which greatly reduces the insulation effect of air. Therefore, the most important thing when using air for insulation is to restrict air flow.

[0025] It's understandable that the smaller the air chamber, the more difficult the airflow, and the better the thermal insulation. However, considering the manufacturability of the structural components, air chambers of millimeter or centimeter size can be fabricated structurally.

[0026] Optionally, in some technical solutions, an air duct is provided inside the outer casing, and the air duct is located outside the air guide cover. When the impeller rotates, air flows into the impeller through the air duct.

[0027] In this technical solution, by setting the air duct inside the outer casing and outside the air guide shroud, an air intake path for the impeller can be provided under the action of the air duct. Specifically, the outlet of the air duct is set opposite to the air intake side of the impeller. For the entire head structure, there can be one or more air duct inlets, and the position of the inlet can be flexibly set to improve the air volume.

[0028] It is understandable that the air duct is located in the space between the outer casing and the air guide cover. This space can serve as a heat dissipation space for cooling internal components, and it can also serve as an assembly space for installing other structures. Of course, the air duct itself has a certain ventilation performance to ensure the normal flow of air.

[0029] It should be added that the airflow generated when the wind turbine is rotating comes partly from inside the wind duct and partly from the rear of the wind turbine.

[0030] A heat insulation layer can be installed on the air duct, and it is also located on the outside of the air guide shroud to isolate the air guide shroud and the heating device to a certain extent.

[0031] In some technical solutions, optionally, at least part of the wind turbine is located inside the wind guide shroud.

[0032] By restricting some or all of the impellers to be placed inside the air guide shroud, the air driven by the impellers when they rotate will flow fully into the air guide shroud. After heat exchange with the air guide shroud, the air is blown outward under the guidance of the air guide shroud, thus realizing the blowing out of hot air.

[0033] In some technical solutions, the heating device may optionally include a heating bracket, which is correspondingly arranged with the air guide shroud, and an electromagnetic coil is wound on the heating bracket.

[0034] In this technical solution, the heating device mainly includes a heating bracket, which is correspondingly arranged with the air guide shroud and located on the outside of the air guide shroud. This helps ensure effective cooperation between the heating bracket and the air guide shroud and provides a stable support structure. In addition, by winding an electromagnetic coil on the heating bracket, an alternating magnetic field is generated after the electromagnetic coil is energized, enabling the air guide shroud to achieve electromagnetic induction heating, providing an efficient method for air heating.

[0035] In some technical solutions, the air guide shroud may optionally be made of a magnetic material, and the heating device and the air guide shroud may be spaced apart.

[0036] In this technical solution, the air guide shroud is made of a magnetically conductive material, and a gap is set between the heating device and the air guide shroud. By using an electromagnetic coil as the heating device, electromagnetic induction heating can be achieved. This method has advantages such as uniform heating and rapid response, which helps improve heating efficiency and control heating temperature. Furthermore, the use of a magnetically conductive material for the air guide shroud helps guide the heat field, improves thermal efficiency, reduces energy loss, and ensures that the heated air can be effectively guided into the air duct, improving the utilization rate of hot air. It should also be noted that the gap between the heating device and the air guide shroud reduces the impact of the high temperature of the air guide shroud on the temperature of the environment where the heating device is located, improving operational safety, and also helps protect the heating device and extend its service life.

[0037] In some technical solutions, the outer casing may optionally include: a detachably connected front mesh cover and a rear mesh cover, the front mesh cover and the rear mesh cover being connected to form a housing cavity for accommodating the heating device, the air guide cover, the impeller and the motor.

[0038] In this technical solution, the outer casing includes a detachable front mesh cover and a rear mesh cover, which together form a cavity housing the heating device, air guide cover, impeller, and motor. The detachable front and rear mesh covers facilitate the maintenance and cleaning of the internal components, making repairs more convenient. This is highly beneficial for the daily maintenance and upkeep of the equipment.

[0039] The cavity formed by the connection of the front and rear mesh covers provides suitable space to house the heating device, air guide, impeller, and motor, allowing these internal components to be effectively installed and secured.

[0040] In summary, this enclosure design improves the ease of equipment maintenance and the stability of internal component installation, which is beneficial to the use and maintenance of the entire system.

[0041] In some technical solutions, the outer casing may optionally include a decorative cover, the two ends of which are detachably connected to the front mesh cover and the rear mesh cover, respectively, and the heat insulation layer is provided inside the decorative cover.

[0042] By setting a decorative cover between the front and rear mesh covers, the appearance of the decorative cover can be customized. On the other hand, the decorative cover can improve user safety and reduce the possibility of burns from the heat of the air guide. It can be understood that there is a gap between the decorative cover and the air guide. On this basis, setting a heat insulation layer on the inside of the decorative cover can further reduce the temperature perceived by the user when touching the decorative cover, thus improving the user experience.

[0043] A second aspect of this utility model provides a heater, comprising: any of the air conditioning devices described in the first aspect; and a base bracket detachably connected to the air conditioning device.

[0044] The heater according to this utility model includes a detachably connected air conditioning unit and a base bracket. The base bracket is detachably connected to the air conditioning unit, which facilitates assembly and disassembly, making the device more flexible, easier to transport and maintain. The base bracket provides stable support, helping to maintain the stability of the entire heater, reducing shaking and swaying during operation, and improving the safety and reliability of the device.

[0045] Furthermore, since the base bracket is detachably connected to the air conditioning equipment, different air conditioning equipment can be selected as needed, making the heater more widely applicable and flexible.

[0046] Additional aspects and advantages of this invention will become apparent in the description that follows, or may be learned by practice of this invention. Attached Figure Description

[0055] To better understand the above-mentioned objectives, features, and advantages of the embodiments of this utility model, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0056] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, embodiments of the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0057] The following reference Figures 1 to 5 Some embodiments of the present invention are described below.

[0058] like Figure 1 and Figure 2 As shown, this embodiment proposes an air conditioning device 100, which mainly includes a housing 102 and a heating device 104, an air guide shroud 106, and an airflow regulating assembly 107 disposed within the housing 102. The airflow regulating assembly 107 includes a fan wheel 108 and a motor 110. Specifically, the housing 102 provides a robust protective shell for the air conditioning device 100, protecting the internal structure from damage and providing heat insulation and electrical insulation to ensure user safety. The heating device 104 is the core of the air conditioning device 100, responsible for converting electrical energy into heat energy. The heating device is positioned corresponding to the air guide shroud, and the heating device raises the temperature of the air guide shroud. Specifically, the heating element can be composed of high-temperature resistant resistance wire, or may use more efficient materials such as PTC ceramic, or even an electromagnetic coil. The air guide shroud 106 is adjacent to the heating device 104, and its inner surface is heated by the heating device 104. The specific shape design should facilitate uniform airflow distribution and heat exchange efficiency. The impeller 108 is located inside the air guide shroud 106. Its rotation generates a powerful airflow, which is heated as it passes through the heated air guide shroud 106 and eventually exits from the front of the head. A motor 110 provides the power to rotate the impeller 108. The motor 110 is designed to ensure sufficient torque to drive the impeller 108 while also possessing good heat resistance.

[0059] It should be added that, for the entire air outlet device, the front side is the air outlet side of the outer casing, and the rear side is the air inlet side of the outer casing, such as... Figure 2 The direction indicated by the middle arrow.

[0060] It should be emphasized that a heat insulation layer 121 is provided between the air guide shroud 106 and the heating device 104 in this solution, which can reduce the temperature impact of the high temperature of the air guide shroud on the temperature of the environment where the heating device is located, improve the safety of use, and also help protect the heating device and extend its service life. In particular, it reduces the temperature impact on the internal electronic components and related structural components after being heated by the heating device 104, and reduces the possibility of damage to structural components or electronic components due to high temperature.

[0061] The heat insulation layer can isolate the air guide shroud 106 and the heating device 104 to a certain extent, reduce the conduction of heat to the heating device 104, thereby reducing the temperature of the heating device 104 and improving the safety of use.

[0062] It is understood that the air conditioning equipment 100 mainly converts electrical energy into heat and mechanical energy to generate hot air. In this solution, by adjusting the relative positions of the motor 110 and the impeller 108, and by adding the structure of the air guide shroud 106, the air is blown into the air guide shroud 106 under the action of the impeller 108. The air guide shroud 106 is heated by the heating device 104, which can increase the temperature of the air blown into the air guide shroud 106. At the same time, the air guide shroud 106 itself can guide the air to the outside of the air conditioning equipment 100 through its structural features, thereby providing warm air with a higher wind speed.

[0063] It should be added that the motor type can be a DC or AC motor, or even a brushless motor to improve efficiency and reduce maintenance; the power and speed of motor 110 must match the design of impeller 108; and the heat dissipation design of motor 110 must ensure that it does not overheat during long-term operation.

[0064] In some embodiments, optionally, such as Figure 3 As shown, by placing a material with low thermal conductivity directly outside the air guide shroud 106, i.e., the heat insulation layer is in the form of a support, forming a heat insulation support 1062, the low thermal conductivity of the material itself can prevent heat from being conducted to the other side of the heat insulation support 1062, thereby ensuring the stable operation of the internal structure.

[0065] It is understandable that by setting the heat insulation layer 121, the high temperature resistance requirements of the heat insulation bracket 1062 can be reduced, which is conducive to cost reduction.

[0066] The air guide shroud 106 is fixed to other structures by means of the heat insulation bracket 1062. It can be directly fixed to the outer shell shroud 102 or fixed to the heating device 104. The heat insulation bracket 1062 can be used as a support structure for the air guide shroud 106 to achieve the limiting function.

[0067] It is understood that in this solution, the air guide shroud 106 is located inside the outer casing 102, and the relative position of the air guide shroud 106 to the outer casing 102 can be restricted by the heat insulation layer 121, that is, the heat insulation layer 121 fixes the position of the air guide shroud 106 inside the outer casing 102.

[0068] In some embodiments, optionally, such as Figure 4 As shown, multiple heat-insulating air chambers 122 are provided on the inner side of the heat-insulating bracket 1062. Utilizing the structure of the heat-insulating air chambers 122, physical heat insulation can be achieved when they are filled with gas. That is, the heat insulation properties of the heat-insulating air chambers 122 themselves are used to block the heat transferred from the air guide shroud 106 to the heat-insulating bracket 1062. Simultaneously, any two adjacent heat-insulating air chambers 122 are separated by ribs 123.

[0069] In some embodiments, the insulating air chamber 122 may optionally be filled with an insulating medium with low thermal conductivity to form a continuous insulating structure, thereby effectively reducing heat conduction and ensuring the normal use of the insulating bracket 1062 and its associated electronic components or mechanical structures.

[0070] Alternatively, the insulation medium can be air. When heated, air expands in volume and decreases in density, causing hot air to rise and cold air to sink (natural convection). In the case of convection, heat is mainly transferred through convection, which greatly reduces the insulation effect of air. Therefore, the most important thing when using air for insulation is to restrict air flow.

[0071] It's understandable that the smaller the air chamber, the more difficult the airflow, and the better the thermal insulation. However, considering the manufacturability of the structural components, air chambers of millimeter or centimeter size can be fabricated structurally.

[0072] In some embodiments, the air duct 114 is optionally disposed inside the outer casing 102 and outside the air guide shroud 106, which can provide an air intake path for the impeller 108 under the action of the air duct 114. Specifically, the outlet of the air duct 114 is disposed opposite to the air intake side of the impeller 108. For the entire head structure, there may be one or more air duct 114 inlets, and the position of the inlet can be flexibly set in order to improve the air volume.

[0073] It is understandable that the air duct 114 is located in the space between the outer casing 102 and the air guide shroud 106. This space can be used as a heat dissipation space to dissipate heat from internal components, and can also be used as an assembly space for the installation of other structures. Of course, the air duct 114 itself has a certain ventilation performance to ensure the normal flow of air.

[0074] It should be added that the airflow generated by the wind turbine 108 when it is rotating comes partly from inside the air duct 114 and partly from the rear side of the wind turbine 108.

[0075] A heat insulation layer can be installed on the air duct 114 and placed on the outside of the air guide shroud 106 to isolate the air guide shroud 106 and the heating device to a certain extent.

[0076] It is important to emphasize that the heat insulation bracket 1062 is fixed to the air duct 114 and is also located on the outside of the air guide shroud 106. The heat insulation bracket 1062 can isolate the air guide shroud 106 and the heating device 104 to a certain extent, reducing heat conduction to the air guide shroud 106, thereby lowering the temperature of the air guide shroud 106 and improving operational safety. Furthermore, the heat insulation bracket 1062, fixed to the air duct 114, provides additional support and stability to the air guide shroud 106, helping to maintain its positional stability, reducing vibration and friction, and improving the reliability of the entire system.

[0077] While isolating and stabilizing the air guide shroud 106, it also helps to improve the working efficiency of the heating device 104, ensuring that the heated air can smoothly enter the air duct 114 and then be pushed out by the impeller 108.

[0078] In summary, the installation of the heat insulation bracket 1062 in this air conditioning equipment 100 helps to improve the stability and safety of the system, while also improving heating efficiency and ensuring the normal operation of the entire system.

[0079] In some embodiments, the heating device 104 optionally includes a heating bracket 1042, which is correspondingly disposed with the air guide shroud 106 and located on the outside of the air guide shroud 106, fixed to the air duct 114. This helps ensure effective cooperation between the heating bracket 1042 and the air guide shroud 106 and provides a stable support structure. Furthermore, by winding an electromagnetic coil on the heating bracket 1042, an alternating magnetic field is generated when the electromagnetic coil is energized, enabling the air guide shroud 106 to achieve electromagnetic induction heating, providing an efficient method for air heating.

[0080] In some embodiments, optionally, an electromagnetic coil is used as the heating device 104, the air guide shroud 106 is made of a magnetically conductive material, and a gap is provided between the heating device 104 and the air guide shroud 106. By using an electromagnetic coil as the heating device 104, electromagnetic induction heating can be achieved. This method has advantages such as uniform heating and rapid response, which is beneficial for improving heating efficiency and controlling heating temperature. In addition, the air guide shroud 106 is made of a magnetically conductive material, which helps to guide the heat field, improve thermal efficiency, reduce energy loss, and ensure that the heated air can be effectively introduced into the air duct 114, thereby improving the utilization rate of hot air. It should also be noted that the gap between the heating device 104 and the air guide shroud 106 reduces the impact of the high temperature of the air guide shroud on the temperature of the environment where the heating device is located, improves the safety of use, and also helps to protect the heating device and extend its service life.

[0081] In some embodiments, the outer casing 102 optionally includes a detachably connected front mesh cover 1022 and a rear mesh cover 1024, which connect to form a receiving cavity for accommodating the heating device 104, the air guide shroud 106, the impeller 108, and the motor 110. The detachably connected front mesh cover 1022 and rear mesh cover 1024 facilitate the maintenance and cleaning of the internal components, making repairs more convenient. This is highly beneficial for the daily maintenance and upkeep of the equipment.

[0082] The cavity formed by the connection of the front mesh cover 1022 and the rear mesh cover 1024 provides suitable space to house the heating device 104, the air guide cover 106, the impeller 108 and the motor 110, so that these internal components can be effectively installed and fixed.

[0083] In summary, the design of this outer casing 102 improves the ease of maintenance of the equipment and the installation stability of internal components, which is beneficial to the use and maintenance of the entire system.

[0084] It should be noted that the structure of the entire outer shell 102 is a fully enclosed structure in the middle, forming a ring shell, with grilles set at the front and rear. At least one of the front mesh cover 1022 and the rear mesh cover 1024 will be designed with an intermediate shell, that is, the intermediate shell can be part of the front mesh cover 1022 or the rear mesh cover 1024.

[0085] By setting a decorative cover 1026 between the front cover 1022 and the rear cover 1024, it can serve as the aforementioned intermediate shell. On the one hand, the appearance of the decorative cover 1026 can be designed; on the other hand, the decorative cover 1026 can improve user safety and reduce the possibility of being burned by the heat of the air guide. It is understood that there is a gap between the decorative cover 1026 and the air guide. On this basis, a heat insulation layer is set on the inner side of the decorative cover 1026, which can further reduce the temperature perceived by the user when touching the decorative cover 1026 and improve the user experience.

[0086] This application proposes another embodiment of the heater 200, such as... Figure 5 As shown, the device includes a detachably connected air conditioning unit 100 and a base bracket 202. The base bracket 202 is detachably connected to the air conditioning unit 100. This design facilitates the assembly and disassembly of the device, making it more flexible, easier to transport and maintain. The base bracket 202 provides stable support, helping to maintain the stability of the entire heater 200, reducing shaking and swaying during operation, and improving the safety and reliability of the device.

[0087] Furthermore, since the base bracket 202 is detachably connected to the air conditioning unit 100, different air conditioning units 100 can be selected as needed, making the heater 200 more widely applicable and flexible.

[0088] In one specific embodiment, an IH sidewall heating fan structure is proposed. The overall structure includes a motor 110, a front grille 1022, a fan 108, a shell (i.e., shell cover 102), a heating element (i.e., air guide 106), a heating element bracket (i.e., heat insulation bracket 1062), a coil disc bracket (i.e., heating bracket 1042), and an air duct (i.e., air duct 114). The overall design uses a centrifugal fan (i.e., fan 108 + motor 110) as the power unit. The centrifugal fan has the characteristics of axial air intake and radial air exhaust, and the outlet airflow is thrown out under the action of centrifugal force. The sidewall of the power unit is made of magnetically conductive metal parts and is heated by electromagnetic induction. During operation, the airflow is heated by passing through the heated sidewall, thereby realizing the warm air function.

[0089] The overall structure is arranged as follows: First, the heating element must be made of a magnetically conductive metal (commonly including 430 stainless steel, iron, etc.). During operation, the heating element heats up due to electromagnetic induction. The heating element is fixed to a heating element bracket, which is typically made of high-temperature resistant plastic (nylon + fiberglass, etc.). The bracket serves two purposes: first, to fix the heating element; second, to provide heat insulation. Since the heating element can reach temperatures exceeding 200 degrees Celsius during operation, conventional electronic components cannot withstand such temperatures, so a plastic bracket is needed to wrap around it, providing some insulation. Outside the heating element bracket is a coil support. An electromagnetic coil is wound on the coil, which generates an alternating magnetic field when energized, thereby heating the heating element. The heating element bracket and the coil support are both fixed to the air duct.

[0090] In one embodiment, a material with low thermal conductivity can be placed directly in the interlayer between the heating element support and the heating element, thereby preventing heat from being conducted to the heating element support through the low thermal conductivity of the material itself.

[0091] In another embodiment, this is achieved through a heat-insulating structure (i.e., heat-insulating air chamber 122). Densely packed small air chambers are created on the heating element support, with the heating element in direct contact with the support. After installation, air is trapped inside the air chambers. Because the heating element support needs to be in direct contact with the heating element, it must be made of heat-resistant materials (such as ceramics or glass) to prevent melting or combustion due to the heat from the heating element. This insulation principle utilizes air as the insulation material. Air is an excellent insulation material when stationary (low thermal conductivity). However, as a fluid, air expands in volume and decreases in density when heated, causing hot air to rise and cold air to sink (natural convection). In convection conditions, heat transfer mainly occurs through convection, significantly reducing the insulation effect of air. Therefore, the most important aspect of using air for insulation is restricting airflow. (Industrial insulation materials, such as foamed materials and aerogels, basically utilize this principle. Through chemical reactions, micron- or nano-sized cavities are formed inside the material. Gas is trapped inside these cavities, restricting its movement, and the low thermal conductivity of the gas itself provides insulation.) The smaller the size of the air chamber, the more difficult the airflow, and the better the insulation performance. However, considering the manufacturability of the structural components, it is sufficient to fabricate air chambers in the millimeter or centimeter size.

[0092] The design of the heat insulation layer primarily addresses issues such as excessively high heating element temperatures leading to overly harsh operating environments and the melting and combustion of plastic components. It also improves the overall heating efficiency of the unit to some extent. When a space heater is operating, its primary goal is to heat the air; heat conducted away through structural components is essentially wasted. By incorporating a heat insulation layer, heat is prevented from being conducted away through the structural components. With a given heating power, this indirectly increases the amount of heat absorbed by the air, thereby improving heating efficiency.

[0093] According to the air conditioning equipment and heater provided by this utility model, the air guide cover and heating device can be isolated by the heat insulation bracket and heat insulation layer, reducing the conduction of heat to the heating device, thereby reducing the temperature of the heating device and improving the safety of use.
